Introduction
A plush jellyfish is one of those crochet projects that feels instantly magical. The round squishy head, sweet little face, and curly tentacles make it cute, calming, and very eye-catching for handmade gifts or nursery decor.
This Luna Swirl Jellyfish Amigurumi is an upgraded original design inspired by the idea in your screenshot: a soft pastel jellyfish with a rounded head and chunky spiral tentacles. This version adds a cleaner dome shape, a soft scalloped underside, mixed tentacle lengths, two accent colors, and a more polished plush look.
The pattern below is created fresh with complete instructions for the head, underside, curly tentacles, side arms, face, assembly, and finishing so the design is buildable and unique.
Description
Luna Swirl is a soft plush jellyfish made with chenille yarn. The head is rounded and slightly domed, with a gentle flat underside so the tentacles attach neatly. The face has simple black eyes and optional tiny cheek details for a sweet expression.
The bottom has a soft scalloped ruffle edge, and the tentacles are made in different styles: long spiral tentacles, shorter chunky curls, and small side curls. This gives the plush more movement and makes it look fuller and more “premium” than a basic jellyfish design.
The sample colors use lavender for the jellyfish head and outer tentacles, with buttery pastel yellow for accent tentacles. You can also make it in seafoam and cream, pink and lilac, aqua and white, or peach and mint.
Materials
- Super bulky chenille yarn in pastel lavender for the head and some tentacles

Pattern Notes
The jellyfish head is worked from the top down in continuous rounds.
The underside is shaped with decreases but left wide enough to attach tentacles.
The scalloped ruffle is worked around the lower edge.
Tentacles are made separately and sewn underneath.
Use stitch markers to track rounds.
For baby-safe toys, embroider the eyes instead of using safety eyes.
Do not make the tentacles too long for babies or toddlers. For nursery decor only, longer tentacles are fine.

Tentacle Layout
Before sewing, lay all tentacles under the jellyfish head.
Suggested arrangement:
- Center area: 3 soft loop tentacles
- Around center: 4 long spiral tentacles
- Between long spirals: 4 short chunky curls
- Outer edge: 4 tiny side curls
Alternate lavender and yellow so the colors look balanced.
Do not place all yellow tentacles on one side.
Attaching the Tentacles
Turn the jellyfish head upside down.
Pin the tentacles around the lower opening.
Sew each tentacle securely to the underside edge or inner bottom area.
Use the long yarn tails from each tentacle.
After all tentacles are attached, place the underside circle over the sewn ends.
Sew the underside circle to the lower opening of the head.
This hides the tentacle joins and makes the bottom look clean.
Face
If you did not use safety eyes, embroider two black eyes between Rounds 10 and 11.
Optional: add a tiny curved smile using black yarn.
Optional: add two small pale pink cheek stitches below the eyes.
Keep the face simple and sweet.

Use lavender yarn.
Join yarn at the top center of the head.

Gently pull the spiral tentacles so they curl evenly.
Trim loose chenille fibers carefully.
Make sure the underside circle is fully sewn down.
Check the face placement.
The jellyfish should hang or sit with a full, balanced tentacle shape.
Size Adjustments
Smaller Jellyfish

Work the same stitch counts.
Make shorter tentacles by chaining 18–22 for long spirals.
Larger Plush Jellyfish

Add one extra increase round to the head:

Shorter Baby-Safe Tentacles
Make all tentacles with chains of 10–14 only.
Avoid long dangling pieces for babies.
Fuller Display Jellyfish
Add 4 more spiral tentacles.
Use three colors instead of two.
Tips & Variations
Use lavender and butter yellow for a soft pastel jellyfish.
Use aqua and white for a clean ocean look.
Use pink and lilac for a sweet nursery version.
Use coral and cream for a warmer plush style.
Use variegated yarn for the tentacles if you want a magical color effect.
Use embroidered eyes for baby-safe plushies.
Use safety eyes only for older children or display toys.
Make the ruffle round slightly fuller by working 5 hdc instead of 4 hdc in each scallop.
For a premium look, add more short curls around the outer edge so the underside looks full from every angle.
FAQ
Is this jellyfish amigurumi beginner-friendly?
This pattern is best for confident beginners. The head is simple amigurumi, but the tentacle layout and underside assembly need careful placement.
Is this the exact pattern from the screenshot?
No. This is a new original plush jellyfish pattern inspired by the visible idea in the screenshot: a round jellyfish with spiral tentacles. The stitch counts, shaping, ruffle, tentacle layout, and finishing details are original.
What yarn works best?
Super bulky chenille yarn works best for a soft plush jellyfish. Worsted yarn can be used for a smaller version.
How do I make the tentacles curl?
Work multiple stitches into each chain. Three half double crochet stitches in each chain create a soft spiral curl.
Can this be used as a baby toy?
Only with baby-safe modifications. Embroider the eyes, keep tentacles short, sew everything very securely, and supervise use.
Conclusion
The Luna Swirl Jellyfish Amigurumi is soft, colorful, and full of movement. The rounded lavender head, scalloped underside, buttery yellow accents, and mixed spiral tentacles make it feel more detailed and eye-catching than a basic jellyfish plush.
Make it as a nursery decoration, ocean-themed gift, handmade plush, or amigurumi collection piece. This upgraded design gives you a cute, buildable jellyfish with every important detail handled from head to tentacles.
